I've collected a handful of picture perfect SW's over the last few years, generally 80 to 150 yd shots with 100gr Pyro RS. One was at 25 yds, hit the off side shoulder blade and zigzagged up into the neck. Bangflop! My current Omega X7 doesn't shoot well over 80gr, tho and was disappointed with bullets performance at slower speeds. I got a big doe at 75 yds, one lung and liver (quartering towards me), complete pass thru and she went over 400 yds. My wife got a small buck with the same load from her Sidekick at ARO 125Yds. Bullet broke the upper leg bone and passed thru as well. He went 200 plus yds, stopped and licked his shoulder and fell over. I don't think either opened up as the exit holes weren't much bigger than the entry. I have a buddy that shoots 150gr Pyro pellets and has a handful of copper "flowers" taken from under the off side hide. His were blowing up until he switched to the bonded ones. I shot three into a 5G bucket of mason sand @ 90 yds before the season and all three were again picture perfect mushrooms. I now have mixed emotions about this bullet. All in all, still a good accurate bullet, but I have my doubts about lower velocity use.
